TYPE-WRITING MACHINE.

Application filed July 31, 1915.

To all whom it may concern:

Be it known that I, BURNHAM C. STiCK- NEY, a citizen of the UnitedStates, residing in Elizabeth, in the county of Union and State of NewJersey, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

The present invention relates to type-' writer. platens which are splitor divided into a plurality of lengths or sections movable individuallyand independently of each other. YVhen the platens are disconnected forindependent use, one division of the platen may, for instance, be usedfor the writing of individual bills or forms, and another division ofthe platen for the writing of ledger accounts, or classified totals, or

general forms taken from the individualstatements. In such a case,thedivision of the platen having the ledger or general sheet thereon issilent while the sheet for the individual statement is placed upon,written on, and removed from another division of the platen; and exceptwhen such general sheet is itself placed or removed, the division of theplaten bearing it only receives line-space movement in the intervalsbetween the writing of individual statements.

In connection with a split or. divided platen, there must be mechanismfor effecting independent line-space movement of the sections, and foreffecting a prolonged independent movement of the sections in insertingthe various features of this invention comprises a platen shaft havingthe ordinary line-space and hand wheels at the lefthand end thereof, butwhich is not permanently connected to either division ufthe plate-n. Thehand wheel at the right-hand Specification of Letters Patent.

lPatcntedUct. 26, 11911.5.

Serial No. cases.

end of the platen frame is carried by a short shaft terminating in asleeve which fits over and is splined to the platen shaft. This sleevecarries a clutch member which mav be shifted by pulling or pushing onthis right hand wheel; and which, according to the direction in which itis shifted, engages either a clutch on the left-hand platen di vision,or a clutch on the right-hand platen division, to connect one or theother of these divisions to the platen shaft. The latter clutch memberis carried by aspider splined to the right-hand platen division andshiftable to engage the clutch on the sleeve at the time the latter islocked to the left-hand platen division, thus causing both divisions tobe locked to the platen shaft for rotation together in ordinary writing.

It is another feature of the present invention to provide operatingconnections for the several platen sections or divisions, such that, anyone section alone, or all together, may receive line-space movement fromone and the same line-space mechanism; or may receive prolonged forwardor reverse move ment individually, 'or together, as a unit, from thehand wheels ordinarilv found on the platen shaft.

In the preferred manner of carrying out the invention, the feed roll orrolls of'each platen section are independent of the feed roll of theother platen section, and are illdependently releasable. Thus a partlywritten sheet may be held by its feed rolls on one platen section whilethe latter remains motionless, and while an entry is heii'ig made upon asheet carried by the other platen section. To this end, I provide foreach platen section a roll-releasing device independent of theroll-releasing device of the other platen section, and I arrange for asingle release key to connect with either of said rollreleasing devices.This connection is preferably effected by the same device that connectsand disconnects the platen sections from the line-spacing mechanism.Thus a single shift of said connecting device will connect one or theother platen section to the line-spacing mechanism, and at the same timeplace the connected live platen section rolls under the control of therelease key, so that said rolls may be released, while the rolls of thedead platen section remain in normal effective positions.

-sections for simultaneous use is not neces- 'sary in all cases, nor isthe connection of both sets of release rolls the single release key. 7

Eeferring to thedravvings'; the platen is sho .vn in two sections; toWit, a left-hand section 10 on which the individual bills or statementsare usuall written and a ri hthand section 11 on which the ledgeraccount, or totals of the individual accounts, are usually Written.These sections are of the same diameter and are concentric with theplaten shaft 12; they abut each other, except that ametal washer orplate 13 is interposed between them to prevent Wear and undue friction,one on the other. The platen sections have the usual vulcanized outershells.

plate of the frame or carriage in which the platen is mounted for itsusual letterteed movement. The shaft 12 1s discontinued at a point suchas 21, in mediate the frame end pieces 20 and 22; hm s supported fromthe right-hand carriage plate by means of a sleeve 23, within which, fora considerable distance, the platen shaft 12 fits. The sleeve 23 at itsright-hand endis continued in the form of a stub shaft 2 which isjournaled in a hub formed on the frame plate integral with the sleevehand end thereof, a disk or clutch memhcr 26. having therethrough a pinhole 27 1 i which a pin :28, carried by m arm 29, in the nature of acrank arnn on a hub or boss 30, which latter is secured by a set screw31 to the platen axle 12. in all positions of the parts, the crank pin28 remains in engagementwith the dish so that, whenever the platen shaft12 is turned, the disk 26 and sleeve must turn as a unit with it. Bymeans, presently to be described, the disk 26 may be locked to eitherone of the platen sections 10 and 11, or to both of them; in order thatline-space movement of the platen shaft 12 may be transmitted to theplatens.

The mean shown for effecting 11 space movement of the platen shaft 12 isthat conimon to the Underwood typewriting machine. On a hub fastto theshaft 12 is a ratchet wheel the pitch between the teeth of whichdetermines the line-syncing when the wheel is turned. The wheel isactuated by means of a pawl 3 lcarried by a slide mounted on the platenframe. A coil spring 2%, the left- 36, secured to the slide and to theframe normally holds the slide forward, and, after each operation,returns it to normal position, with the pawl out of engagement with theratchet wheel. A linger lever, in the form of a bell-crank pivoted tothe carriage frame at 37, has one arm 38 having a linger-piece 39, andanother arm 40 which engages and forces back the slide, to turn thelinespace wheel, when the finger-piece is pressed to the right. A springdetent (not shown) engages the line-space wheel to hold the parts inposition for printing. The platen shaft and connected parts may also beturned by means of the left-hand wheel 41, fast to the shaft 12 or bymeans of the right-hand wheel 42, fast to the stub shaft 24; the lattershaft, as above pointed out, being connected through the sleeve 23 forrotation as a unit;

with the shaft 12.

' position of the disk.

messes Diametrically' opposed, and projecting from the internalperiphery of the platen 10, are two. teeth 2:5, shaped at 46 to engagebetween adjacent teeth t7 on one side of the periphery of the disk 26.These teeth on the disk 26 are, in number and pitch, the same as theteeth on the linespace wheel 33. When, therefore, the parts are in Fig.8 position, with-the disk teeth :7 in engagement with the teeth 45 onthe platen 10, the platen 10 must turn as a unit with the linespacewheel on operation of the latter. This is the condition of the machinewhen only the platen 10 is to receive line-space movement; that is tosay, when an indi-v vidual statement or bill is being written, the totalof which is later to be transferred to the ledger sheet on the platen11.

Sincethe platen 10 is to be idle while the totals or other writings areentered upon the ledger or other sheet on the platen 11, it becomesnecessary for this purpose, to disengage the disk 26 from the teeth {lon the platen 10. To this end, the sleeve 23, on which the disk 26 ismounted, is slidable longitudinally on the platen shaft 12 from Fig. dto Fig. 5 position. The hand wheel l2 conveniently serves as a means foreffecting this shift of the disk. The pin 28 on the crank arm 29 is longenough to hold the disk 26 against angular displacement on the platenaxle whatever the longitudinal In this shifting operation, not only isthe right-hand platen disengaged from the platen axle 12, but theleft-hand platen 11 connected to the platen axle for movement therewith.The connection of the axle to the platen 11 is effected through a secondset of teeth l8, on the periphery of the-disk 26. but on the righthandedge thereof; the teeth 4:8. like the teeth d7, corresponding in numberand angular position to the teeth on the line-space wheel Interlockedfor rotation as a unit with the platen 11 is a spider t9, the

arms of which at their ends have teeth 50 engaged in recesses 51 in theinner shell of the platen ll. The spider l9 is mounted on a sleeve 52which embraces and bears upon the sleeve 23 but which at times is freeto turn independently of the latter. lVhenever the spider is turned,however, the lefthand platen 11 must turn with it, because of theinterlocking connections 50 and 51. When the disk has been shifted toFig.

9 position, it will be noted that it is locked to the spider l9 byreason of the engagement of the laterally projecting teeth 53 on thearms of the spider with the teeth t8 on the disk. At this time,therefore, a linespace movement of the line-space wheel 33 must resultin a corresponding movement of the left-hand platen 11, while therighthand platen 10 is idle.

The; clutch member or disk 26 is held against accidental displacement inits several positions by' means of'a ball clutch ordetent consisting ofa ball 5%, seated on a compressed coil spring 55, which is held in apocket 56 in a lateral extension of the disk 26 opposite the boss or hubof the crank arm 29. In alinement on the hub 30 are two ball notches orpockets 56 and 57; the pocket 56 registering with, and holding the ball5%, when the parts are in Fig. 8 position; and the pocket 5. doinglikewise when the parts are in 9 position. The pocket 56 is slightlybellied to the left to tend to draw and maintain the teeth of the disk26 in close engagement with the teeth on the platen 10, so that playbetween the platen axle and the platen 10 may be eliminated; and thepocket 57 is similarly bellied to the right to hold the disk in suchengagement with the spider 49 that play between the platen axle and theplaten 11 may be eliminated. The platens are thus so held that properalinement of the letters and spacing of the lines are assured.

Platens l0 and 11 may be locked together, and to the platen axle, sothat they may be turned as a unit when the machine is to be used forordinary writing purposes. To this end, the recesses 51, by means ofwhich the spider i9 engages the platen 11" are elongated to permit thespider to be shifted longitudinally from Fig. 8 position to Fig. 6position. The spider is actually splined to the platen 11. In Fig. 8position, the clutch member or disk 26, which at all times turns withthe axle 12, is fast to the platen 10. The shift of the spider from Fig.8 to Fig. (5 position causes the teeth 53 on the spider arms to engagethe teeth l8 on the disk 26 in the same manner as when the disk isshifted to the spider. In this way, the platen 11, through the spider49, is locked to the disk 20, to which the platen 10 is already locked;and the two platens as a unit must turn with the platen axle. This shift.may also be made when the parts are in Fig. 9 position, in which event,the shift of the spider causes the disk 26 to be moved with it to Fig. 6position. For shifting the spider T9, the sleeve on which it is mountedis extended through the right-hand end plate 58 of the platen 11, whereit is thread ed at 59. Having a flange,or bearing 60, within an openingin the plate 58, and threaded into the sleeve 52 is a knurled nutGlwhich has a shoulder at 62 to abut the plate 58, and which is extendedat '63 to abut the carriage plate 22. This nut therefore has no movementlongitudinally of the platen axle, and rotation thereof mustconsequently cause the sleeve 52 and spider 4C9 to be shifted along theplaten axle in one direction or the other, according to the direction ofrotation of the nut 61. To look the platen 11 to the platen axle. thenut 61 to be capable of use independently of the.

other, each is preferably provided with a pair of front rolls and a pairof back rolls.

As is customary in Underwood typewriting machines, the back rolls arepreferably all mounted on one shaft 68, and the front rolls all on oneshaft 69. In order, however, that when one platen alone is used, themovement thereof may not be transmitted through the rolls and rollshafts to the other platen, the rolls are all loosely mounted on theirshafts. The shaft 68- is carried on arms 70 pivoted to the shaft 71; andthe shaft 69 is carried on arms 72 likewise pivoted to the shaft 71.Arms 70 form bellcranks with arms 73, and arms 72 form bellcranks witharms '74. Springs hold the rolls against the platen and hold the arms7.3 and 74 against flats 75 on a rock shaft 76. To permit freewithdrawal of the paher from either platen division, the rolls 65 and 66may be thrown off of the platen by means of a linger-piece 77 on an arm78, pivoted to the platen frame at 79, and form ing a bell-crank with anarm 80. Attached at one end to the arm 80, and at the other end to anarm 81 on the rock shalt 76, is a link 82. Depressionof the fingerp'iece77 draws up the link to rock the shaft 76, thereby causing the flats 75thereon to be so,

turned as to force apart the arms 73 and 7%, thus removing the rolls 65and 66 from the right-hand platen; all of which rollsupporting andreleasing mechanism is common in Underwood typewriting machines.

It is desirable when using the right-hand or left-hand section of theplaten to bring the co-acting sets of feed rolls of the respectivesections of the platen under the control of the finger-piece 77 so thatit mav actuate that set of feed rolls coacting with the active sectionof the platen, that is, the section which may at the time be coupled tothe line-spacing mechanism. Mechanism is also provided to bring bothsets of feed rolls under the control of the finger-piece 77, so thatboth sets of feed rolls may be actuated thereby when both sections ofthe platen are coupled to the line-spacing mechanism.

' Upon the typewriter carriage is a bracket 83, on which is mounted alever 84, the upper end of which is forked at 85 to embrace the stubshaft 24. A spring 88 causes said fork to bear against a hub 86 on thehand-wheel 42. The lower end of the lever 84 has a slot 87, throughwhich the link 82 passesf When i the hand-wheel 42 is moved leftwardlyto igieaeoe engage the left section of the platen with the line-spacemechanism, as shown in Fig.

4, it causes the lowerend of the lever 84 to be swung rightwardly,carrying with it the link 82, the lower end of which has a perforatedboss formed thereon to engage a pin 89 formed on an arm 90 of therollreleasing rock shaft 91, which rock shaft has flat surfaces 91formed thereon, which form cams to actuate or control thebell cranks 92and 93, on which are mounted the front and rear feed rolls that coactwith the lefthand platen or section. It will be seen that if new thefinger-piece 77 is actuated, the feed rolls of the left section of theplaten will be released, while the feed rolls of the right-section ofthe platen will remain in their normal positions. This is because therightward adjustment of the lower end of the link 82 has disconnectedsaid link from the arm 81 (fast on the shaft 76 which actuates theright-hand set of feed rolls. But when the hand-wheel 42 is re-set fromthe F 1g. 4 tothe Fig. 5 position, to connect up the right-hand sectionof the platen with the line-spacing mechanism, the lower end ofthe lever84: will be moved leftward, carrying with it the link 82, so that thelatter will become disengaged from the pin 89 on arm 90, and he movedinto engagement with a pin 94 on the arm 81. Thereafter, any niotion ofthe finger-piece 77 will be transmitof feed rolls will therefore remainin their normal positions when the finger-piece 77 is actuated.

In order to connect both sets of feed rolls I to the finger-piece '77when desired, there is mounted on the bracket 83 a lever 95,'the upperend of which has a pin-and-slotconnection 96 with a sliding pin"orfollower 97 which passes through the boss 25 provided on theright-hand plate 22 of the platenframe. The inner end of said pin 97 ispressed against the right end of the sleeve 52 by means of a spring 99,which is connected to the right-hand carriage plate and causes the lever95 to follow the lateral shifting motion of the sleeve 52. The lower endof the lever 95 is forked at 100 to fit in an annular groove 101 formedin an extension 102 on the shaft 76, which is slidably mounted in itsbearings. When the. parts are in position so that the left-hand sectionof the platen is connected to the line-space.

engagement with the link 82, as shown in Fig. 6. It will be seen that nthis position both pins 89 and 9% are in en agement with the link 82,and will transmit any motion imparted to the finger-piece 77 to theirrespective feed rolls. When the knurled nut 61 is rotated to move thesleeve rightward from the Fig. 6 position back to the Fig. 4 position,to silence the right section of the platen, the slide 97 will be movedright- Wardly therewith, and through lever 95 cause the pin Ell tobecome disconnected from the link 82, thus leaving the link 82 inconnection with the pin 89, so that the left-hand set of feed rolls willbe actuated, while the righthand set of feed rolls remain in theirnormal position upon the actuation of the finger-piece 77.
